RC水塔结构的抗震性能探讨分析
|
摘要
本文采用有限元分析软件对不同支承高度和不同水箱储水量RC水塔结构的抗震性能和地震反应进行了空间有限元地震响应分析,对比了反应谱法和时间历程分析法在水平地震作用下的弹性地震反应结果,研究了支承高度和水箱储水量对水塔的动力特性和地震响应的影响,提出了RC水搭抗震设计的注意事项和具体建议,供实际工程参考。
In this paper,the time history analysis and response spectrum analysis to seismic wave were performed with ANSYS software,based on the numerical study,the dynamic response characteristics of the reinforce concrete tower in the case of different height and different water reservation were discussed and the two type analysis results were be compared,the research work can provide a reference for the seismic design.
